Kate Middleton stepped out in public on Tuesday for a good cause – and for the first time since announcing she is expecting her third child.
The Duchess of Cambridge joined husband Prince William, and brother-in-law, Prince Harry, to celebrate World Mental Health Day.
At a special Buckingham Palace reception, they honored those working in the mental health field and at their Heads Together campaign.
This initiative, headed by Kate, Harry and William, aims to reduce the stigma surrounding mental health issues in the UK and worldwide.
They did not discuss what Kate Middleton’s baby gender and name, but her baby bump was ever-so-slightly visible, as you can see below!

Happy to Be There

The event marked KateâÂÂs first public outing since August 30, when she and the royal brothers marked the 20th anniversary of the death of Princess Diana.
On the Upswing

As with her first two pregnancies, Kate has been suffering from Hyperemesis Gravidarum, an extreme form of morning sickness that forced her to cancel her public duties.
Doing Their Part

William, Kate and Harry were praised by those in the mental health community for their work to break down stigmas surrounding issues of anxiety, depression and more.
In Praise of Kate

William thanked everyone for what theyâÂÂd done and said it was Kate âÂÂwho first realized that all three of us were working on mental health in our individual areas of focus. She had seen that at the core of adult issues like addiction and family breakdown, unresolved childhood mental health issues were often part of the problem.âÂÂ
A Royal Round of Applause

Writer and activist Fiona Millar told reporters that William touched upon shifting attitudes among younger generations on the subject of mental health. âÂÂHe was saying about people in the Great War not wanting to talk about their emotional experiences, and then passing it on to their children … the stiff upper lip, âÂÂDonâÂÂt talk about how we feel,âÂÂâ said Millar. âÂÂTo be perfectly honest, that is a bit of a trademark of the royal family. And it obviously has its place. But the fact that they came out and did talk so openly about their feelings was a real shock to a lot of people. They donâÂÂt expect the royals to do that.âÂÂ
The Public Face of A Crucial Issue

Philippa Creasy, who lost her husband Terry to suicide five years ago, says Kate, along with her husband and Harry, âÂÂundoubtedlyâ can take the issue of mental health forward: âÂÂTheyâÂÂre the only three who can do it. No one could change the conversation like theyâÂÂve done.âÂÂ
